Britney Spears F-Bomb: Britney Drops F-Bomb After ALS Ice Bucket Challenge [Video]

Britney Spears completed the ALS Ice Bucket Challenge on Monday, and dropped the F-bomb after the icy cold water was dumped on her head! The Piece Of Me singer posted the video of her Ice Bucket Challenge on Facebook and Instagram on Monday after being nominated by her sister, Jamie Lynn Spears. Following most of the rules, Spears stated her name, said who nominated her, and then nominated three people to take on the challenge to raise awareness for ALS.

Brit nominated actor Adam Sandler, her beau David Lucado, and her personal assistant, Robin Greenhill.

Britney Spears then got a large bucket of ice water dumped on her, knocking off her sunglasses, and causing her to swear from the shock of the freezing cold water. Of course Britney is not the only person who has sworn after completing the challenge either. Most people are so freezing cold and soaking wet after completion that they swear in some capacity, even if they don't mean to. It's just the body's reaction! Almost everyone lets out a shriek at the very least.

Britney cut off her video just before she got the whole word out, but fans quickly caught her swearing as she walked out of the picture. Other celebrities that have completed the Ice Bucket Challenge to #StrikeOutALS include Justin Bieber, Niall Horan, Lena Dunham, Ben Affleck, Justin Timberlake, and Kaley Cuoco-Sweeting. For the record, none of them swore. As previously reported by The Inquisitr, Kaley from The Big Bang Theoryaccepted the challenge on Sunday after being nominated by Josh Gad and Nick Wilder.

In other Britney news, the songstress was recently accused of lip-synching at her show in Las Vegas (gasp!). According to Mail Online, a rep for the singer denied reports that Britney was mouthing the words to Sia's voice -- the two previously recorded an acoustic version of Brit's song Perfume. Britney's rep says that the version that Britney was singing at her show didn't feature Sia and that the voice that was coming through the speakers was indeed Britney's (sigh).

Britney Spears is back in Las Vegas for more shows at Planet Hollywood. She has a pretty full schedule through 2015, and whether she is lip-synching or not, plenty of people are making the trip to Vegas to see her. Ticket prices range from $59 to $500 with VIP and Meet and Greet tickets reaching over $2,000 each.
